Convert df column to datetime format

[LarsCordes]

You should pass date format parameter to pandas.to_datetime.

YYYY-mm-dd -> '%Y-%m-%d' -> format='%Y-%m-%d'

Thanks, but I have tried it specifying these formats in a few different ways, and it continues to return the same error "ValueError: to assemble mappings requires at least that [year, month, day] be specified: [day,month,year] is missing"

The pandas.to_datetime documentation states that it should take an argument as 'integer, float, string, datetime, list, tuple, 1-d array, Series'. Does a df.column meet any of these definitions, or does it need to be converted into a Series or np.array or something first?
